The numeral keys 2, in addition to ty writing, control computi'ngoperations. l dr this pur ose, each of the numeral keys is 6, which, in turn, draws on a link '7. The link 7 is connected to rock a bell crank 8, Fig. 15, nivotally mounted on a spider .9. The helhcrank 8. thrusts forward a plun er 0r. jaCk-1Q-,.So as to set the app'ositeoneo a series '0f;pll1'S 1'1, adjustably. mounted on. a pin-wheel'12. There is a series of the plungersor jacks L0, one-for eachnumeral key, and they correspond in their positions inthe circle inE which they are arranged to the values of the associated numeral keys.

The;pin1-wheel .12forms an escapement or indexing.wheel,.,which determines the extents ofzcomputationstocorre'spond with the particular numeral keys'operated; For this purpose, normally, all of them, but one, pr'o ect. toward flheplungers or jacks 10 and are held'in-such positions by means of a circular spring 13, which vmay engage alternately an-a .pairiof grooves 14 and 15 pro vided-in-the. 1118211. One of the pinsll is normallyheld: with its right-hand end- ('Fig. 16) =projeetedi.and engaging a stop-wheel 16, Fig-5. Thisistop'rwheel prevents the rotationof pin-wheel 1-2 in the manner to be presently described, until a numeral key is actuated. 9

The pin-wheel- 12 is normally under a driving tendency to rotate from amotor 17, F igi :3. The motor 17 is connected in. the manner more particularly described in the parent caseby a train of gearing 18 to a shaft 19, to which the pin-wheel 12 is socured. This train of gearing includes a slip clutch (not shown), which, so long as the pin-wheel 12 is held by the stopfwlieeli 16, will permit the motor to run idly without drivingthe pin-wheel, but. as soon as the pin-wheel is released by rotation of the stopwheel-16, then the motor will drive the shaft 19 and the com uting mechanism controlled by the shaftan'dlbv the pin-wheel.

The stop wheel 16 is normally held against rotation until a numeral key is actuated. For this purpose, it is secured to a shaft 20, on the other end of which is provided a starswheel engagement with a sto disk 22 011 a; rockzshait 28. The stop-dis 22yl1asan=openihg 24 therein, which, when theshaft 23 is rocked, will come in register with the-particular tooth or arm of the star wheel 21, which happens to be in engagement with the disk 22. V This will permit the to a hook 5, and when depressed draws down on his hook to rock a bell crank 21, one of the teeth of 5 set up one of the star-wheel21to escapeuntil it is caughtby a secondstop-disk 'l0cated-1ju'st beyond the stop-disk 22 and secured to the same rock shaft 23. 'I he second stop-disk 25 has an opening or apassage 26 out of register with the passage or opening 24 on the first stop-disk22, so; that it will. returnor backward rocking; movement of the disks and shaft, to. permit the tooth of the starwhee1 21,,which has just escaped fromthedisk 22;- to; escape from theidisk- 25. The back-and-forh rocking movementiof the, shaft 23.-is controlled from the, numeral keys at the striking ,of'themto print and to gins 11 For .t ispurpose each of the links is provided-,witha hea 27,1 ig. 15, which when the associated nu.- meral key is operated engages and operates a plate, 28, universal to alloi the heads 27. This plate 28 is mounted on a rod-29,;guided for sliding movement, .and. has connecte thereto ,a 1 lever 30, p ivoted. intermediate its ends. When. a numeral key. sets; one; of the.

On returnvof the numeral. ey, however, the. shaft 23 rocks backwardly, permitting the star-wheel.2l.to escape from the second disk 25, which will rotate the stopfrom the disk mits but a slightrotation 16, notsufiicient, however,

Under these conditions, theindexing pinwheel, 12 will rotate until the just .set pin comes into enga ernent with the stop-wheel gin-wheel 12 will be broughtlto astop by t enext tooth of the stop-wheel 1.16 which. is rotated enou h-to bring she, next arm ofthestarwhee .21 :intoengagemen't with thefirst stop vdisk 22. The previously --,projected pin is returned during. 1 the notation :of {the wheel 12:bya properly'locatedcam 34". l g

,The amount of rotation of the indexing pin-wheel 12.:depends on the n'umerahkey *just actuated, which .will set a pin 11 at a distance-from the stop-wheel 16, corresponding to its value.- This escapement ing'mechanism, 'herefore, valuates the computing action according to theparticular numeral he I struckz In other terminesthe extents which the -mot0r 17 will drive the computing wheels-of totalizers 34"an'd 35 step by step as the numeral keys are-operated.

The'connection from the indexing shaft necessitate the just far or indexwords, it *de- 19 to the totalizers 34,and-35 includes a beveled gear 36 secured to theshaft 19. This beveled gear 36 meshing with a gear 37 on a shaft 38 provided with a beveled gear 39 meshing, with a gear 40 to drive a vertical shaft 41. The ertical shaft 41 drives master wheel shafts-42 and 43 for the totalizers 34 and 35,;respectively. A reversiblegearing connectionis provided between the vertical shaft41 and each of the master wheel shafts 42 and-43, so that oneinaster vheel shaft may be rotated to add, while the other is vrotated to subtract. This connection is alsoarranged so that .one master wheel shaft maybe-disconnected or-silenced, while the othe riisactually driven. F or this purpose, the shaft is provided. with four beveled gears, 44, 45, 46 and 47, arrangedin oppositely facing pairs and loosely mounted on the shaft-41. One pair of gears, 44 and 45, mesh with and drive mbeveledgear 48 secured;.to the masterwheelshaft 42, while the, pair of gears,;46 and .4 7,' mesh with and drive abeveled gear '49 securedto the masterwheel shaft 43. ,1 oydetermine which gear ofieach pair shall be clutched in drivingrelation with the shaft ,41, there is provi ed betweeneach paira 'clutch,.indi cated at 50, for the totalizer 34', and ,at'51 for the totalizerf 35. These clutches have teeth at their aipper and lowerlends ,to engage cor responding teeth-provided on lthe inner faces on the gears 44 to 47. The clutches 50 and 51 are -splined on the shaft 41, so as to rotate therewith, and can move from an intermediateneutral' position, in which they are not connected with either. of the beveled gears of a pair, to either lone of. two positions on opposite sides of this neutral position, in which they will connect onefor the other of the pair" of beveled ears rigidly to the shaft 41. It is thus evi ent that the motor 17 ma drive the master wheel shafts 42 and 43 either separately or in unison and either inthesame direction or the opposite directions. -11; w

The'master w eelshafts 42-.and 43 are squared, .as illustrated. 'in Fig, .1, so as to drive .master heels 52,and;53 for thetotalizers 34 and 35,- irespectivelyr These master wheels are slidably Fnounted on. the shaftsz42 and 43, so that they can be brought step by step into register with internal gears 54, rovided on computing wheels 55, Fig. 7. he computing wheels 55 are also provided with external gears 56, which mesh which meshes with and drives a gear 62. The gear 62 is interposed between the rack 61 and oppositely-facing rack 63, so as to drive the latter at the same speed, but in the opposite direction. The rack 63 is provided on a master-wheel carriage 64 for the master wheel 52 of the totalizer 34. This carriage 64 is slidably mounted on ways 65, so as to have a rectilinear movement. It will thus be seen that as the typewriter carria e 4 advances step by step in a letterfee ing direction, the master-wheel carriage 64 will advance step by step to the right, Fig. 1, carrying the master wheel 52 ceriatz'm into register with each of the comput ing wheels 55 and dial wheels 58, startin with the wheel of highest denomination and advancing one by one through the series of wheels to the wheel of lowest denomination. The master wheel 52 is moved with the master-wheel carriage 64 by a sleeve66, Fig. 8, which has a circular tongue-and-groove connection 67 with the master wheel 52, and

a second circular tongue-and-groove connection 68 with the carriage 64. In thisway,

the master wheel 52 may rotate with the shaft 42 relatively to the sleeve 66 and the master-wheel carriage 64, and yet can be moved positively lengthwise of the shaft 42 as the carriage 64 advances step by step.

At this point it may be stated that the totalizer 34 is a. long'totalizer andincludes a. long series of computing wheels,'one computing wheel for each digit column desired to be computed in within the capacity of the typewriter carriage 4. These computing wheels may be computed in in groups to correspond with the grouping of the digits in major columns or computing zones as typewritten on the work-sheet carried by the typewriter carriage. This is taken care of by the proper spacing of the major columns of numbers as typewritten with the proper movement of the typewriter carriage to the several computing zones. Each of the groups of computing wheels as predetermmed upon will compute vertical columns of figures, so that the 1011 totalizer 34 will give a series of sum tota s, one for each vertical column typewritten and computed.

The other totalizer 35 is a short totalizer and is adapted to cross total and also gross total. That is to say, it is adapted to sum up the numbers typewritten in horizontal columns, at the same time that these members are individually summed up by the long totalizer 34 in vertical columns. For this purpose, the master wheel 53 for the short cross totalizer 35 is'made to move in svnchronism with the master wheel 52 for tie long totalizer 34. These movements, however, are intermittent, that is tosay, the master wheel 53 will move in synchronism with the master wheel 52 for the range or capacity of the short cross totalizer '35 and for a group' of the computing wheels of'the long totalizer 34. Then, it will jump back and start over'again in synchronism with a new cup of computing wheels of the long tbta izer'34.

For the purpose ofvibrating the master wheel 53, it is connected intermittently to travel with the master wheel 52 and its carriage 64. On the carriage 64 there is provided a rack 69, carrying a series of teeth located at lettersspace-intervals, and also at computing -wheelspace intervals. This-rack 69 'fonnsaccura'te means of adjustin'g'pick iipstops 70at computing wheel emulates-space inteevals by] inserting the stopsbetweew the teeth of the rack. The picleup'etops may be locked in their ad justed' positions by set screws 71 engaging m openings w, pr'oviddmn. th'eZ'one oi -the rack '69: The number the pick-up-stops 7O jar' provi'ded {according to the number of separate" computing zones or columns de-' siege-, and they are derived at positions correspondihgfto the-location of the initial digit column 'offeach -niajor computing zone orcolhm'ii ds typewritten on the work-sheet carried bytliecafria ge. The pick-up stops 70 form a part of the means of connection between the long totalizer master wheel carriage 64 and a carriage 73 for the short totalizer master wheel 53.

Each of the stops come in succession into engagement with a hook 74, provided on the short totali'zer master wheel carriage 73, and enters'into a socket 75 provided in this hook, asprin'g 76 forcin the hook 74 onto the stop 70. The initia pick-up stop 70 carries the short totalizer master wheel carriage 73 along with it until the master wheel 53 has computed "in the units computing wheel, when an incline or cam surface 77 comes into engagement with a disconnecting cam 78 lyin in the path of travel of the hook 74. This cam 78 will cause the hook to be forced out of engagement with the initial pick-up stop 70, so as to disconnect the short totalizer master wheel'ca'rria e 73 from the long totalizer master wheel carriage' 64.

During the travelof the" master wheel 53 from the highest computing wheel of the short totalizer to the lowest computing wheel, a, rack 79 on the short totalizer carria e 73 drives a ear '80 to wind up a spring-drum" 81. bus, when the short totalizer carriage 73 is disconnected from the long totalizer carriage 64, this springdrum 81 unwinds to return the master wheel carriage 73 and the master wheel 53 to their starting position. In this position, the hook 74 is ready to be engage b the next pick-up stop 70, so as to cart t e master wheel 53 along in unison witi the master wheel 52 for the second group of computing ment with the wheels of the long totalizer 34. The advance and return oscillation of the short totalizer master wheel 53 is repeated for the length of travel of the long totalizer master wheel 52 until allof the zones and grou )s of computing wheels have been compute in.

In order that the long totalizer carriage 64 may not return the short totalizer carriage 73 and the master wheel 53 beyond the registering of the master wheel 53 with the highest computing wheel on a return movement of the typewriter carriage and the carriage 64, there is provided a disconnecting cam 82, which is arranged to en age the cam surface 83, provided on the hoo 74,so as to depress it against the tension of the spring 76, and thus clear the book 74 from enga eparticular pick-upxstop 0 in register with it, and permitting all stops to the right thereof to clear themselves from the hook by depressing it, one after another, as they pass over it. The spring 76, however, holds the hook 74 up so that the first stop 70, traveling to the ri ht, will accurately centered by the tapered member just to the right or in advance of the masterwheel, as seen in Fi 8.

Considering the d rive from the motor 17 to the assisting rollers 90 for the totalizers 34 and35, a train of gearin 91, (Figs. 1 and 3), connects the shaft 0 the motor 17 with a transverse shaft 92, so as to constantly rotate the latter. The shaft 92 drives, through theintermediary of a air of gears 93and 94, a vertical shaft 95. his vertical shaft 95 is-provided with two pairs of oppositely-facing gears, one pair for each carry-over assistin roller 90. These gears are numbered 96, 9 98 and 99. The gears 96'and 97 drive a beveled gear 100, secured to a shaft .101,-on which the assisting roller 90 for the upper long totalizer 34 is mountpick up the book 74 and carry a ong the.

master wheel 53. The positions of the master wheels 52 and 53, with respect to the computing wheels are pointed out by indicators 84 and 85.

Provision is made for carrying complete rotations of lower computing wheels and dial wheels to higher computing wheels and higher dial wheels of both'totalizers. For this purpose, each of the computing wheels is provided with a carry-over tooth 86, Figs. 4 and 7. This carry-over tooth engages and operates once in a revolution a five-toothed gear 87, Fig. 6. The five-toothed gear 87 forms one element of a carry-over unit, which includes three parts, to wit, the gear 87, a five toothed star-wheel 88 and a gear 89. The gear 89 meshes with the car 56 of the next higher com uting whee from the one which operates t e gear 87 through the intermediary of the carry-over tooth 86. When the carry-over tooth 86 operates the carry-over unit, it brings one of the teeth of the star-wheel 88 within -the driving range-of an assisting or boosting rubber roller 90, so that the latter will complete the carry-over movement of the carry-over unit, causing the digit 1 to be carried from, a lower computin wheel to the next higher computing whee The assisting roller 90 is driven from the motor 17 in one direction or' the other, according to whether the master. wheel for the associated computing wheel is rotated for addition or for subtraction.

The computing wheels 55 are normally supported and retained in place by gears 89 of the carrg-over mechanism, the gears 57 of o the dial w eels, and the gears 115 (see Fig. 7). As the computing wheels 55 .are ape5 proached ,by the master-wheel 52 they are ed. The gears 98 and 99 drive a similar gear 102 for the shaft 103-, on which the assisting roller 90 for the lower short total izer 35 is mounted.

The paired gears 96 to 99 are not secured to the vertical shaft 95, but may be individually connected thereto by means of clutches 104 and 105 for the upper totalizer 34 and .the'lower totalizer 35, res ectively. These clutches are provided wit teeth on their upper and lower ends, and may be shifted from an intermediate neutral position in which they connect neither of the paired beveled gears to the shaft 95, to alternative positions, inwhich they may connect either the upper beveled gearor the lower beveled gear of the respective pairs, in driving relation with the shaft 95, In this way the tens-carrying assisting rollers may be driven or not, and driven in either one d1- rection or the other selectively from the shaft 95 to corres 0nd withthe drive and the direction of rive of their associated master wheels.

In order to shift the'master wheel clutch in unison with the tens-carryin clutch for each totalizer, there'is provide a shifting lever, indicated at 106, for the upper long totahzer 34, and at .107 for the lower, short totalizer 35.' Each of these shifting levers is pivoted at its rear end and carries a pair of pins 108, one to engage the tens-carrying clutch and the other to en go the master wheel clutch. Thus, bot shifted in unison for a given totalizer, rendering the same active or silent and when rendering a totalizer active, determining whether the carry'over roller and the master wheel shall be rotated for addition or for subtraction. Each lever extends to the front of the machine, where it is provided nipulated. Just in rear of this clutches are grilp, each lever engages a detent bracket 111 1g. 9), p

which is provided with three sockets 112, 113 and'114, into which the lever 106 may be sprung to retain it in 329 three positions of the lever and theassociated clutches. Thus, the clutches will be locked'in any one of their three positions, correspondin to whether the associated totalizer is adfing, neutral, or subtracting.

The operation of the invention will be readily understood .when taken in connection with the above description. As stated above, this case is a division of the parent application, above-mentioned, and covers a modified form, whereby vertical totalizing and cross with gross totalizing can be concomitantly carried out, using a long and a short totalizer. At the start of the initial computing line on the work-sheet, the typewriter carriage 4: is located at the extreme right of its travel; and then positioned to bring the initial computing zone or major column on the work-sheet to the printing point of the typewriting mechanism. This zone has been predetermined upon in any usual way; as, for example, b the use of properly set tabulat' mec anism. To

correspond with this se ection of the computing zones or major columns, the pick-up stops are adjusted at proper intervals alongthe rack bar 69.

Under such circumstances, the master wheel 53' for the short cross totalizer-35 will be in register with the initial computing wheel of this totalizer at the same time that the master wheel 52 will be in register with the first computing wheel ofthe first group of computing wheels corres nding to the initial com uting 'zone. T l first pickaip stop 70, t at is, the one farthest to the right of Fig. 1, will be in engagement with the book 74, forming a positive connection between the two master wheel carriages, so that they will travel in unison. As the digits are printed one by one, they are likewise run up .into the computing wheels serz'atim, the typewriter carnage driving the long totalizer master wheel carriage 64, which, in turn, carries the short totalizer master wheel carriage 73 along with it.

When the final or units digit is computed in the first number for the first computing zone or major column, the short totalizer master wheel carriage .73 is disconnected from the long totalizer master wheelcarriage 64 by the hook 74 running into the disengaging cam 78 as the t pewritericarria 4 jumps out of the units ctter-space on t e return of the numeral key striking the digit for the units place. This enables the spring drum 81 to return the short totalizer master wheel carriage 73, bringing the master wheel 53 in register with the computin wheel of highest denomination, in' the 5 art totalizer 35.

The carriage 4 is then spaced to, bring the next major column. or com ut' zone to the printing point, which will Van e the two master wheels 52 and 53, skipping one or two of the highest com uting wheels in the second group of the ong totalizer 34 and the short totalizer 35, to allow for the carry-over from the lower computing will be computed separatelyin the second group of computin wheels of the long totalizer 34: and'will added to the number already accumulated in the short totalizer 35.

The short totalizer master wheel 53 will escape as before, whenthe number of the second vertical column is completely written and com uted, enablin the computin of the initia number in t 1e third vertica column. This is repeated for as many vertical columns as are provided'for by the pick-up stops 70, so that at the end of the rst line, there will be a series of individual numbers, one for each vertical column, accumulated in the long totalizer 34, and the sum of this series accumulated in the cross totalizer 35.,

For one type of work, the accumulated cross total of the first line may remain in the short totalizer 35, and the o eration re- V one for each vertical column, while the cross totalizer 35 contains the gross total, including all of the numbers typewritten and computed, the short totalizer 35, however, having accumulated them in a cross total manner, while the lon totalizer 3-1 accumulated the sums, indivi ually, vertically. Both totalizers can then be shifted for subtracting and the sum totals in each group of computing wheels of the long totalizer copied and computed. If the work has been done correctly, the groups will be cleared to zero one by one, and the cross totalizer will be cleared to zero, forming a check on the work.

For another type of work, the last group of computing wheels of the long totalizer 34 can be reserved to transfer the accumulated cross total of the numbers vertically summed up in the remainder of the groups of computing wheels of the long totalizer -3-1, so that at the end of each line, the number exhibited b the cross totalizer 35 will be written on t e work-sheet, thereby running it and cleared at the'end of a line by simply making the long totalizer 34 add Whilethe short'totalizer 35 subtracts, thus exhibiting in the last group of computing wheels of the long totalizer 34 the gross total at any particular time. i ()n the final line of the work-sheet the sums accumulated in the several groups of com utin wheelsof the long totalizer 3-lare cop1edo on the work-sheet, after, first, however, shifting the lever '106 of the long totalizer 34 to subtraction. Thus, each sum will be cleared from the longtotalizcr 34,-,returning the computing wheels to zero as these vertical sdms are written on the work-sheets. lhe short totaliz'er 35 is, however, at the same time. adding, and will add up in a cross totalizing'manner the sum of the vertical sums until the final column is reached. Then, when the final column is reached, the number exhibited by the last group of computing wheels of the long totalizer 34 should'correspond to the number exhibited by-the shortto'talizer 35. The lever 107 for the short totalizer can then be "shifted tosubtraction, while the lever 106"of the long totaliaer 34 remains in the, subtracting position, aiidthenumber, which is the gross total of item'numbers written on the work-sheet, can be copied, on the work-'sheet,whereby it will be simultaneously cleared out of the last -oup of computing-wheels of the long totalizer 34'and cleared out of thescomputing wheels of the short totalizer 35. In this way, an accurate check on the work may be had, and when a worksheet is completed with the vertical totals, the cross totals and the gross total all computed 'and written on the work-sheet, all the computingwheels of both totalizers will be at zero, permitting the machine to be used for another piece of. work on a new work-sheet, without need of manipulating the computing wheel s. i
